Chapter 4. MTCH6301 Utility Layout

4.1 INTRODUCTIONThe MTCH6301 Utility displays by default a Welcome window that explains the basic features of this utility. The utility contains five tabs (see Figure 4-1):• Setup• Auto-Tune• Self (disabled by default)• Mutual (disabled by default)• Touch

FIGURE 4-1: TABS OF THE MTCH6301 UTILITY

The main window is also split into five sections (see Figure 4-2):• Basic Parameters

• Visualization

• Help

• Information

• Advanced Parameters

FIGURE 4-2: SETUP TAB WITH EACH SECTION HIGHLIGHTED


MTCH6301 Utility Layout

4.2 SETUP TABThe Setup tab is designed to correctly match the controller’s pin layout with the sensor. The Basic Parameters section contains two boxes to input the number of RX (Receive) and TX (Transmit) pins that are used to connect to the sensor. The Visualization section initially displays how the controller believes the sensor is laid out. The default setting for the MTCH6301 is 12 RX and 9 TX channels. If the sensor has a different layout than shown, drag the appropriate RX or TX pin from the controller to the correct location on the sensor. When the sensor is correctly laid out, click the Set Pin Map Registers button to apply the settings on the controller. Finally, in the Information section, the status of the controller will be displayed along with the controller’s firmware version, the controller’s ID and the version of the utility (see Figure 4-3).

FIGURE 4-3: SETUP TAB WITH PIN MAP BEING MODIFIED

4.2.1 Advanced Parameters SectionThe Advanced Parameters section of the Setup tab allows advanced interface components and features to be enabled (see Figure 4-4). Specifically, the menu and toolbar can be displayed, along with enabling the Self and Mutual tabs. If the controller needs to be restored to the factory defaults the Restore Factory Defaults button can be clicked. If clicked, text will appear after a few seconds indicating if the restoration was successful. Finally, the Perform Manufacturing Tests button checks the controller for any pin faults. The status of the controller will appear next to the button after the tests are performed.

FIGURE 4-4: ADVANCED PARAMETERS SECTION OF THE SETUP TAB



4.3 AUTO-TUNE TABThe Auto-Tune tab is designed to tune the MTCH6301 for a balance of report rate speed and sensor accuracy. Some applications may need additional tuning (see Section 4.4 “Self Tab” and Section 4.5 “Mutual Tab” for more details). The steps of the Auto-Tune procedure are shown in the Visualization section and described in the Information section. The Auto-Tune procedure is broken down into six steps (see Figure 4-5):1. Starting the Auto-Tune Procedure2. Setting the Sensor Flip State Parameters3. Gathering the Self and Mutual Baseline Values4. Setting Basic Self Parameters5. Setting Basic Mutual Parameters6. Finishing the Auto-Tune Procedure

FIGURE 4-5: START SCREEN OF THE AUTO-TUNE PROCEDURE

4.3.1 Starting the Auto-Tune ProcedureTo begin the Auto-Tune procedure click the Start Auto-Tune button found in the Basic Parameters section (see Figure 4-6).

FIGURE 4-6: START AUTO-TUNE BUTTON



4.3.2 Setting the Sensor Flip State ParametersAfter the Start Auto-Tune button is clicked, the procedure will begin by displaying the first of three targets. These targets are used to determine the orientation of the sensor, also known as the Flip State. For each target, tap the equivalent quadrant of the sensor. The utility will automatically detect the touch and move on accordingly (see Figure 4-7).

FIGURE 4-7: SENSOR FLIP STATE SECTION OF THE AUTO-TUNE PROCEDURE

After tapping the third target the utility will determine the orientation of the sensor. Do not touch the sensor during this time.

4.3.3 Gathering Self and Mutual Baseline ValuesAfter the utility calculates the orientation of the sensor, it will proceed to collect self and mutual capacitance data to use as a baseline. Self capacitance refers to a measurement taken from a single RX line on the sensor and mutual capacitance refers to the measurement taken from a single RX/TX node on the sensor. It is very important not to touch the sensor during this time.



4.3.4 Setting Basic Self ParametersThis step of the Auto-Tune procedure collects the self capacitance data used for tuning the controller. To complete this part in the procedure, the sensor must be touched approximately in the center, such that the red bar directly above the green square is the highest. Then, the touch should be adjusted so that the two adjacent bars become equal in height (see Figure 4-8). When the utility determines that a touch is in the correct location, a progress bar on the right side of the graph will fill up. Once the bar is completely filled, the utility will collect all the self capacitance data needed to tune the controller.

FIGURE 4-8: SELF GRAPH OF THE AUTO-TUNE PROCEDURE

After the self capacitance data is collected, the utility will switch to the Mutual Auto-Tune graph.

Note: The graph in Figure 4-8 collects data from the RX axis. Depending on the rotation of the sensor, the touch may need to be moved up and down or left and right in order to get the expected results.

Note: To ensure an accurate Auto-Tune procedure, please note that the user should not touch the sensor while the utility is switching between graphs.



4.3.5 Setting Basic Mutual ParametersThe goal of this step in the Auto-Tune procedure is to touch the controller so that a blue dot appears and navigates into the box in the center of the graph. Once the dot is in the box, the progress bar on the right will start to fill up (see Figure 4-9). When full, the utility will capture the mutual capacitance data from the controller.

FIGURE 4-9: MUTUAL GRAPH OF THE AUTO-TUNE PROCEDURE

4.3.6 Finishing the Auto-Tune ProcedureAfter the mutual Auto-Tune graph completes, the data collected is analyzed by the utility to determine the final parameters. The resulting values are saved to the controller’s registers. These values are the Self Scan Time, Self Threshold, Mutual Scan Time and Mutual Threshold. These registers may be viewed and fine-tuned by enabling the Self and Mutual tabs in the Show Advanced Parameters section of the Setup tab, by clicking the Register Data Window icon on the toolbar which can be shown via the Show Advanced Parameters section of the Setup tab or by saving the registers to a file.

Note: Keep moving about the sensor until the blue dot appears. This box is an expanded view of a section of the sensor. A touch may move the blue dot very quickly while trying to navigate the dot inside of the box.



4.4 SELF TABThe Self tab is designed for manual tuning of the self capacitance measurements of the MTCH6301 controller with your sensor. The Basic Parameters section contains the same parameters used by the Auto-Tune procedure to tune the controller. The two register values that can be changed are Self Scan Time and Self Threshold. The Self Scan Time register value refers to the quantity of measurements taken on each RX line, while the Self Threshold register value refers to the level an RX line must achieve before it is further analyzed for a touch.The Visualization section contains the Self graph that displays the measurements taken from each RX line in real time. The Information section shows a snapshot of the base-lined self capacitance data so that the values are readable. Self packets may be logged in real time by clicking the Start Logging button (see Figure 4-10). When clicked, this button will prompt to select a location for saving self data. To stop logging self data click the Stop Logging button that appears in the Information section.

FIGURE 4-10: SELF TAB



4.5 MUTUAL TABThe Mutual tab is designed for manual tuning of the mutual capacitance measurements of the MTCH6301 controller with the user’s sensor. The Basic Parameters section contains the same parameters used by the Auto-Tune procedure to tune the controller. The two register values that can be changed are Mutual Scan Time and Mutual Threshold. The Mutual Scan Time refers to the quantity of measurements taken on each RX/TX node, while the Mutual Threshold refers to the level an RX/TX node must achieve before it is further analyzed for a touch.The Visualization section contains the Mutual graph that displays the measurement taken from each RX/TX node in real time. The Information section shows a snapshot of the base-lined mutual capacitance data coming in every tenth of a second so that the values are readable. Mutual capacitance packets may be logged in real time by clicking the Start Logging button (see Figure 4-11). When clicked, this button will prompt to select a location for saving mutual data. To stop logging mutual data click the Stop Logging button in the Information section.

FIGURE 4-11: MUTUAL TAB



4.6 TOUCH TABThe Touch tab is designed for verifying that the controller is tuned and is outputting the correct touch locations (see Figure 4-12). Gestures can also be turned ON/OFF.

FIGURE 4-12: TOUCH TAB

4.6.1 OverviewThe Basic Parameters section contains four items:• Flip State• Gestures turned ON/OFF• Ability to save the registers to the controller’s NVRAM• Ability to save modified registers to a fileThe Flip State determines the orientation of coordinates that are sent from the controller. The available checkboxes provide multiple combinations to achieve any required orientation. Gestures are a list of predefined touch movements that can be turned ON or OFF. Only gestures from Touch ID 0 are shown in the Visualization section of the Touch tab. However, in the Information section gestures from all touch IDs are shown.



The gestures supported by MTCH6301 are as shown in Table 4-1.

FIGURE 4-13: TOUCH TAB WITH GESTURES ENABLED

There are two buttons in the Basic Parameters section (see Figure 4-13):• Save to Controller• Save to FileWhen clicked, the Save to Controller button saves all of the registers to the controller’s nonvolatile memory. The Save to File button determines which register values have been modified from the factory defaults and saves them to a .csv file. This file provides a reference for what parameters need to be changed in a manufacturing scenario. This file can also be imported into the utility at a later time to easily configure additional MTCH6301 controllers.To use the current settings in a manufacturing scenario open the Register window (Toolbar or Menu must be enabled) and ensure that the custom view is chosen. Based on the register values shown, a series of Set Register commands will need to be executed on the target controller. To view the format of these commands open the Raw Data window (Toolbar or Menu must be enabled) followed by selecting a few registers at a time in the Register window and clicking Write. Finally, use a firmware command to write the register values to nonvolatile memory.



4.6.2 Visualization SectionThe Visualization section shows a graph of the sensor based on the amount of RX and TX channels (see Figure 4-14). The graph can show up to ten touches where each touch is a different color, as shown below:• Touch ID 0: green• Touch ID 1: red• Touch ID 2: yellow• Touch ID 3: blue• Touch ID 4: dark cyan• Touch ID 5: purple• Touch ID 6: white• Touch ID 7: pink• Touch ID 8: orange• Touch ID 9: sky blue

4.6.3 Advanced Parameters SectionThe Diagnostic Graph may be enabled by selecting the Show Advanced Parameters and Diagnostic Mode in the lower left corner (see Figure 4-15). This gives a visual representation of how the controller determines the location of a touch. The red line represents the self capacitance data. Once an RX line reaches a potential touch threshold, it performs a mutual capacitance scan represented by the blue lines. The yellow lines indicate the search process that MTCH6301 undergoes while looking for the maximum activation level. Points that are not a true maximum are eliminated in favor of the adjacent, more activated values. The closest node to a touch is shown by the gray line and dot on the grid. Finally, the touch is determined and shown in the same color as the coordinate graph.

4.7 MENU AND TOOLBARThe menu and toolbar are enabled in the Advanced Parameters section of the Setup tab. They are designed to easily navigate to some of the advanced features of this utility (see Figure 4-16).

FIGURE 4-16: MENU AND TOOLBAR

The icons located in the menu and toolbar from left to right are:• Open• Save• Save As• Raw Data Window• Register Window• Send Commands• Register Offset• Baseline Controller• Freeze/Thaw• Help• Toggle Connection

4.7.1 OpenThe Open icon ( ) allows loading of previously saved configuration value files. When a file is selected, the values are then loaded into the controller’s registers.

4.7.2 SaveThe Save icon ( ) will overwrite any currently loaded file that is being used. If no file has been currently opened, then a window will pop up asking what the name of this file should be. When the file being saved to is determined, all modified register values are saved to the file.

4.7.3 Save AsThe Save As icon ( ) opens a window asking what file name should be used to save the modified register values on the controller.



4.7.4 Raw Data WindowThe Raw Data icon ( ) opens a window which lists all raw byte data coming from the controller (see Figure 4-17).

FIGURE 4-17: RAW DATA WINDOW

4.7.5 Register Data WindowThe Register Data icon ( )opens a window that shows any registers that have been modified from the factory defaults. To view all of the registers click the Show All button. To read or write registers check the corresponding checkbox to the register and click the Read or Write button (see Figure 4-18).

FIGURE 4-18: REGISTER DATA WINDOW



4.7.6 Commands WindowThe Commands Window icon ( ) opens a window that allows commands to be sent to the controller (see Figure 4-19). The controller will send a response for each message.

FIGURE 4-19: CONTROLLER COMMANDS WINDOW

4.7.7 Register Offset WindowThe Register Offset icon ( ) is an advanced feature that allows valid register byte offsets to be read or written (see Figure 4-20). By default, the values are displayed in decimal. However, to display the value in hexadecimal, start the field with the prefix ‘0x’ (for example, 0xFE). To provide the value in binary, start the field with the prefix ‘0b’ (for example, 0b11001111).

FIGURE 4-20: REGISTER OFFSET WINDOW



4.7.8 Baseline ControllerThe Baseline Controller icon ( ) will perform a software baseline or a hardware baseline to correct potential problems with the controller.

4.7.9 Freeze/ThawThis icon ( ) will freeze any Data Visualization section graph and Information section text data. This allows an easy way to see how the graph correlates to the data.

4.7.10 HelpThe Help icon ( ) opens the Welcome window if it is not currently open. The Welcome window explains the basic features of the utility.

4.7.11 Toggle Connection This icon ( ) toggles between connecting and disconnecting the controller from the utility.


USER’S GUIDE
Chapter 5. Troubleshooting

5.1 THE AUTO-TUNE PROCESS FAILS AFTER THE FLIP STATE TARGETSSome video card drivers have trouble rendering the self and mutual Auto-Tune graphs which can cause the utility to fail. The solution is to first open the Windows Registry Editor, search for and run regedit.exe. When the Registry Editor is open search for showSelfText (the register should currently be set to true) and change this value to false. Then search for showMutualText (the register should currently be set to true) and change this value to false. This should fix the utility’s failure during the Auto-Tune procedure.

5.2 THE MTCH6301 UTILITY INSTALLER REQUIRES ADMINISTRATOR ACCESSThe MTCH6301 Utility requires administrator access for installation. If the desired installation computer does not have administrator rights, please contact a user that has administrator rights in order to install the utility.

5.3 SOME OF THE VISUALIZATION GRAPHS HAVE LATENCY ISSUESThe MTCH6301 touch controller reports information very quickly and it may report at a faster rate than a video card can process and render. The current recommendation is to use a more powerful graphics card solution. It is recommended that a video card with at least an average G3D mark of 60 is used from http://www.videocardbenchmark.net/.

5.4 SOME OF MY TOOLBAR WINDOWS ARE NOT VISIBLEIn some rare circumstances, the floating or dockable windows may become positioned so that it is no longer possible to access them. To correct this, first exit the MTCH6301 Utility if it is running. Then browse to the application directory of the utility (for example, it is often under C:\Program Files\Microchip\MTCH6301Utility or C:\Program Files (x86)\Microchip\MTCH6301Utility). Finally, double-click on the file restoreSoftwareDefaults.reg. The system will respond with a dialog reading “The keys and values contained in <current path>\restoreSoftwareDefaults.reg have been successfully added to the registry”. The next time the utility is run, all of the application defaults will be used.

5.5 RESTORING DM320016 TO FACTORY DEFAULTSTo restore DM320016 to factory defaults complete the following steps: 1. Disconnect DM320016 from all devices before turning the SW1 power switch to

the OFF position and the SW2 switch to the DEV position.2. Connect the PKSA that came with the development kit to DM320016 using the

left header, PKS, on the device.3. Open the MTCH6301 Utility and click the Show Advanced Parameters checkbox

in the lower left hand corner, which will display a list of additional options, including a Restore Factory Defaults button. Click the button and wait for the “Controller factory defaults restored” text to appear.

4. Close the utility and disconnect DM320016. Once DM320016 stops receiving power from PKSA, factory defaults will be restored.

5. To verify that the device has been restored move SW2 so that DEMO is selected and change SW1 to the ON position.
